Delay in second dose of Pfizer / Biotech or Modern vaccines United Kingdom Has saved lives, according to a modeling study United States, Which suggests that other countries are struggling to vaccinate their populations.
The second shot of both vaccines and the Oxford / AstraZeneca whenever the manufacturers design it to be given within three to four weeks of the first dose. The UK has chosen a 12-week delay between meals to get as many people as possible vaccinated as soon as possible.
Immunological evidence has shown high safety with a single dose – up to about 80% with both Pfizer and Moderna, both of which are similarly formulated MRNA vaccines. In the UK, there is also evidence from the immunization program that people who have been given a dose of the Aster Zenica and Pfizer vaccines are less likely to be hospitalized with covid.
The U.S. study, from scientists at the Mayo Clinic in Rochester, found a second dose of the Pfizer and modern vaccine – which reflects the effect of the two delays used in the United States – in populations where vaccines are in short supply due to global shortages. Rollout is slow.
They found that delaying the second shot would save as many lives as possible. They say that in people under the age of 65, where the vaccine is 80% effective and only 0.1% to 0.3% of the population is vaccinated daily, 47 to 26 deaths per 100,000 people can be avoided. Is.
